I think the point is that if your robot is 60" tall when flat on the floor, and is driving down off a tilted bridge, you will be much taller than 60" measured from the floor when you first touch the carpet.

Not quite. Imagine that there's a plane where your wheels touch the carpet. This plane moves with you, no matter how tilted your robot is, and the 60" ceiling is measured from that.

The rule Gary quoted was to emphasize that the 60" rule does not apply until your robot contacts the carpet. You're safe on the bridge, but as soon as your front wheel touches the carpet, you had better be no more than 60" tall.

The 60" rule applies at ALL times. So, if you are using a shooting device that extends above your robot while shooting, that additional height counts. For example, a catapult that arcs over the top of the robot must count the catapult at its highest point. If that causes the bot to exceed 60", then you can't use your shooter while on your side of the court.

Exactly. The FIRST Q&A answer may also help clarify:

A. The vertical measurement is always in relation to the Robot.
